Swing Dampener Brake Joint Assembly for Easier Boom Servicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Servicing of swing dampener brakes in joint elements installed in boom assemblies is difficult, requiring dismantling of the entire joint element or removal of hydraulic hoses, making maintenance cumbersome.
Innovation Solution
A joint element design with a swing dampener brake that allows the second end part to be moved to a detached position axially, enabling servicing from outside the joint assembly without disturbing hydraulic hoses, while maintaining radial load-bearing capacity, using a splined shaft coupling and adjustable operating system to transfer torque and apply friction for damping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the joint element is designed as a integrated unit, then the structural strength and rigidity are improved, but the ease of repair deteriorates because servicing requires dismantling the entire joint element
Solution Approach 1:
The joint element is divided into separate modular components: a first joint part, a second joint part, and a swing dampener brake assembly. The coupling mechanism allows these segments to be detached from each other, enabling the swing dampener brake to be serviced independently without dismantling the entire joint element, thus resolving the contradiction between structural strength and ease of repair.
Solution Approach 2:
The swing dampener brake is extracted as a separate serviceable component from the main joint element structure. The coupling mechanism enables the second joint part (containing the brake) to be detached and removed from the first joint part, allowing the brake to be taken out for servicing while the main joint structure remains intact, maintaining overall strength while enabling easy repair.
2Ease of repair
If the joint element is disassembled for brake servicing, then the ease of repair is improved, but the loss of time increases due to complete dismantling and reassembly
Solution Approach 1:
By segmenting the joint element into detachable parts with a coupling mechanism, only the necessary second joint part containing the brake needs to be detached for servicing. This selective disassembly significantly reduces the time required compared to complete dismantling, while still providing easy access to the brake for repair.
Solution Approach 2:
The coupling mechanism is pre-designed to allow quick detachment and reattachment of the second joint part. This preliminary preparation of the coupling system enables rapid servicing operations without requiring time-consuming complete disassembly and reassembly procedures, thus reducing loss of time while maintaining ease of repair.
3Ease of repair
If hydraulic hoses are removed for brake servicing, then the ease of repair is improved, but the device complexity increases due to additional connection and disconnection operations
Solution Approach 1:
The second joint part containing the swing dampener brake is extracted as a separate unit that can be serviced without removing hydraulic hoses. The coupling mechanism enables this extraction while leaving the hydraulic connections intact on the first joint part, thereby simplifying the servicing procedure and reducing device complexity compared to hose removal methods.
Solution Approach 2:
The coupling mechanism acts as an intermediary that allows separation of the second joint part from the first joint part while maintaining the integrity of hydraulic connections. This intermediary coupling enables brake servicing without disturbing hydraulic hoses, reducing the complexity of connection and disconnection operations.
4Ease of repair
If the second joint part is detached from the first joint part, then the ease of repair is improved, but the radial load-bearing capacity deteriorates
Solution Approach 1:
The coupling mechanism provides dynamic functionality, allowing the second joint part to be detached when needed for servicing and reattached when not needed. This dynamic capability enables temporary separation without permanent loss of load-bearing capacity, resolving the contradiction between ease of repair and radial load-bearing capacity.
Solution Approach 2:
The coupling mechanism is pre-designed to maintain radial load-bearing capacity when the parts are connected, while allowing controlled detachment for servicing. This preliminary design ensures that the structural integrity and load-bearing capability are preserved during normal operation, and can be temporarily suspended only when intentionally detached for maintenance purposes.

Function Achieved in This Case
Facilitates easy servicing of swing dampener brakes without relocating hydraulic hoses, maintaining radial load-bearing capability, allowing for efficient maintenance and extended service life of the joint element.
Implementation Method 1
The swing dampener brake comprises first and second brake disc members, each having an active surface adapted to cooperate with another active surface to dampen the swinging between the first joint part and second joint part
Implementation Method 2
The second joint part is bearing-mounted to the first joint part by a bearing assembly for turning around a turning axis

AI summary
A joint element provided with a swing dampener brake and comprising a first joint part (2), a second joint part (4), and the swing dampener brake. The second joint part (4) comprises a first end part (41) and a second end part (42) which is detachably fixed to the first end part (41) by a joint part coupling which is adapted to transfer torque between the first end part (41) and the second end part (42), and the joint part coupling is adapted to allow the second end part (42) to be moved in an axial direction to a detached position in relation to the first end part (41), the detached position allowing the replacement of active components of the swing dampener brake while the first end part (41) remains bearing- mounted to the first joint part (2).
